I wired my tree with 500 LED lights and calculated their 3D coordinates #piday #raspberrypi @Raspberry_Pi
In the olden times the most complex problem for lighting up your christmas tree was finding the single burnt out bulb. Stand-up Maths works through the joys of NeoPixel Christmas trees. The result of a coordinated 3D array really pays off.
Here is my code on github (along with the 3D coordinates of all 500 LEDs on my tree). If you have a program you would like to see run on my tree, email me firstname.lastname@example.org https://github.com/standupmaths/xmast…
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
